| 摘 要： | 提出一种储罐液位测量的新方法,利用储罐内液体加注时所激发声音的频率变化进行罐体内液位的测量.首先基于空气共振腔的共振频率理论建立了罐体液位与共振频率间的关系,并利用实验获取的声信号数据验证了理论的正确性,在此基础上设计一个基于嵌入式处理器的液位测量系统.

| Abstract: | A new technique of liquid level measurement is introduced. This novel technique makes use of the phenomenon that the resonant frequency excited by the sound of liquid impact will change with the liquid level when liquid is infused into the tank. The relationship between the resonant frequency and the level is investigated in theory as well as by the experimental results. Based on the research aforementioned,a novel liquid level measurement system is developed based on the single-chip processor. |
